Primordial soup, also known as prebiotic soup, is the hypothetical set of conditions present on the Earth around 3.7 to 4.0 billion years ago. It is an aspect of the heterotrophic theory (also known as the Oparin–Haldane hypothesis) concerning the origin of life, first proposed by Alexander Oparin in 1924, and J. B. S. Haldane in 1929.

The 2015 NASA strategy on the origin of life aimed to solve the puzzle by identifying interactions, intermediary structures and functions, energy sources, and environmental factors that contributed to the diversity, selection, and replication of evolvable macromolecular systems, [2] and mapping the chemical landscape of potential primordial ...
Since then, the primordial soup theory (Oparin–Haldane hypothesis) has become the foundation in the study of abiogenesis. [88] [89] [90] Although Oparin's theory became widely known only after the English version in 1936, Haldane accepted Oparin's originality and said, "I have very little doubt that Professor Oparin has the priority over me ...

The concept of the primordial sandwich was proposed by the chemist Günter Wächtershäuser to describe the possible origins of the first cell membranes, and, therefore, the first cell. [ 1 ] According to the two main models of abiogenesis , RNA world and iron-sulfur world , prebiotic [ 2 ] processes existed before the development of the cell ...
In his 1868 book The Variation of Animals and Plants under Domestication, Darwin said the topic was "quite beyond the scope of science". [15] Though it was not published during his lifetime, a letter written by Darwin to botanist Joseph Dalton Hooker on 1 February 1871 proposed the prescient idea that abiogenesis may have occurred in a shallow lake environment,: [1]
Alexander Ivanovich Oparin (Russian: Александр Иванович Опарин; 2 March [O.S. 18 February] 1894 – 21 April 1980) was a Soviet biochemist notable for his theories about the origin of life and for his book The Origin of Life. He also studied the biochemistry of material processing by plants and enzyme reactions in plant ...
